Part of the percieved aggressivness may be locale also.
Diving in the carribean I have never encountered any triggerfish that appeared aggressive.
Diving in the Gulf of Mexico, it's not uncommon for people to get bit by triggerfish. It doesnt necessarily happen only to people who are spearfishing either, and they seem to especially like ears.
When descending along a rig leg, you can see half a dozen or more coming out from the structure to check you out. Usually they turn and leave you alone, but every once in a while one will dart in for a nibble. I've had to poke more than one with a spear tip to fend them off. And this was before I'd shot anything with nothing on a stringer.
YMMV
